It's like that children's trick where you take someone's birthday, add, subtract, multiply and divide it with some numbers and then guessing the original number from the result. That, but taken several steps further. It's honestly magical to me every time I think about it. P.S.

<a href="#" class="seekto" data-time="186">3:06</a> - Not only did real-time DEcoding of Morse Code come as a surprise to Morse and manufacturers, but real-time ENcoding wasn't anticipated either. There many things that nobody thought humans could do until humans were doing it. The original intent with Morse was that you'd use the codebook to translate the message's letters (and maybe some punctuation) into dots and dashes, then completely lay out the message using metal slugs (short ones for dots, long ones for dashes) in a rack or on a drum. With the message already composed, you'd step up to the wires and turn a switch that would turn on a slow-turning drum at the telegraph wires' other end. That drum was coated with paper or something similar, and a pencil (or something similar) was pointed perpendicular to the drum's circular surface, towards the drum's axis. The switch's current also rang a bell at the receiving station, to tell someone to be sure to have paper on the drum for a soon-to-be-incoming message. The pencil was held by electromagnets (or something similar) so that with current applied (miles away), the pencil would be pressed into the paper on the drum, and when the current was interrupted, the pencil would rapidly retract. Then the sender would run their rack (or drum) of dots and dashes over the contacts, which, miles away, completed the circuit around the pencil and caused it to write long and short marks (the dashes and dots), separated by empty white space, on the drum's paper. People at the receiving end would then use the code-sheet to change the drum's paper's dots and dashes back into letters. At the time of Morse code's inception, nobody knew that the process of changing letters into dots-and-dashes at the sending-station and the process of changing dots-and-dashes back into letters at the receiving-station would soon be done without cheat-sheets by people who could do it entirely in their head, FROM MEMORY of the code-sheet, and IN REAL TIME, which made sending a Morse message more like talking back and forth and less like typesetting a broadside for a printing-press.

@@chiaracoetzee Well, the paper on the drum could be turned inside-out and reused. The pencil (or ink) would of course have a finite life. The rack of short and long slugs that completed the electrical circuit miles away from the pencil would just be taken apart and reused for dost and dashes the next time a message was sent. I have surmised that the ability to read a music-score in real time (a.ka. "sight-reading") was also a surprise. The original intent with scores was that they were ways you could FIGURE OUT what music to sing, and go over it several times, a bit faster each time, to learn it, much as we expect actors in a play to have read the script in advance to have learned it. You had the score with you when performing, but it was just a memory-guide, like a teleprompter for words you have already memorized anyway. But as time wore on the human mind turned out to be capable of going straight from page to concert-hall AT TEMPO.

However, i think since most colors are too similar and that would be a problem for the reader to read, they would reduce the number of color bits.

when I first used QR codes I thought the QR stand for "Quick Read" but Quick Response is much more viable
One cool thing you can do with QR codes that intend to contain proprietary data, such as an inventory tracking app, is encode the data as a parameter to a URL. The app will know to expect that URL to say “these are the codes we are looking for” but also as a way for a generic code scanner to redirect any given code to an App Store to download the correct app. Of course this introduces some privacy concerns but something like a container ID may be harmless to send.

Yes, why this is different from NFC or cards, is you would definitely find stores which don't accept anything but cash in many countries, but with India's QR codes, it's as easy as downloading an app to setup a QR. The apps in fact have hired people to go to each and every merchant in their assigned cities and convince them to setup their app and QR codes. It is just Direct bank-to-bank transfer without any intermediary. Mediums like Visa, MasterCard, or phone wallets charge either the customer or merchant. All you need is a bank account and a smartphone to setup your QR for free, while you need to pay merchant fee to the likes of Visa on every transaction and buy the card scanner machine. This is why small stores across countries charge extra if you pay with card.

Correction: Strictly speaking, ASCII is only 7 bit, not 8 bit. ASCII is 0 through 127 (128 code points in total). Numerous other character sets have extended ASCII for utilizing 8 bits and beyond. Without getting into the details, we often use UTF-8 nowadays, which is a superset of ASCII.

Correct, however "ASCII" is still often the term used, even incorrectly. I think this is just because it is much easier to say "askey" than "U T F - 8" or "UNICODE". Similar to how the modern ethernet cable connector is commonly referred to as RJ45 when it is actually an 8P8C connector. Much easier to say RJ45 than 8P8C. Like "ASCII art" is still called ASCII art even though it's almost certainly residing on a webpage utilizing UTF-8. I mean... is it still technically ASCII if there aren't any characters that strictly make use of UTF-8's encoding scheme, even if UTF-8's encoding scheme is being used? If you create a .cpp file, write only backwards compatible C code, and compile it with a C++ compiler and it compiles without error, was that C or C++ code you just wrote?

This is such an awesome video! I never knew so much about barcodes and their origin, and now I understand how they work and why. I work at a grocery store and deal with barcodes all day long, hundreds of times a day. Every time I stock a product, I check the UPC (universal product code, or barcode) to make sure I am putting the right product in the right spot. Usually I only check the last 2 digits, which is usually sufficient enough as long as you are in the right section and are fairly sure it goes where you are putting it. For example, when stocking different flavors of the same product. Also, I was always told not to enter the last digit of a barcode when ringing up an item, or entering it into the computer system, but never knew why! Now I have an all new respect for something I had no idea was so intricate and well designed!

@@TomisaMaker The Talos Principle is a first-person puzzle game developed by Croteam and published by Devolver Digital, released in December 2014. The game masterfully combines intricate puzzle mechanics with a deep, philosophical narrative that delves into themes of consciousness, existence, and what it means to be human. In the game, you awaken as a sentient android in a mysterious world filled with ancient ruins and advanced technology. Guided by a voice known as Elohim, you're tasked with solving a series of increasingly complex puzzles to prove your worth. As you explore, you'll encounter terminals that reveal fragments of the world's backstory, prompting you to question the reality of your existence and the nature of free will. What's great about The Talos Principle is its seamless blend of challenging gameplay and thought-provoking storytelling. The puzzles are engaging and well-designed, offering a satisfying sense of accomplishment without feeling repetitive. The game encourages players to reflect on profound philosophical questions, making it an underrated gem that leaves a lasting impression long after completion. This game very deeply touched my psyche in a way that few or no other games have. It very strongly resonated with my worldview: there's no obvious god around us, but we're able to explore the universe, create meaning from an absurd universe, and create solutions to problems from life. Perhaps there's a way to transcend it everything: to become greater than a god we can imagine. Even without free will: we and the whole univerae can change for the better. Plus, now there's a second Talos Principle and more DLC and story for the game's universe. There will likely be a third Talos Principle: the writers are already writing the third game. Tldr: The Talos Principle 1 is a philosophical puzzle game about what it means to be a person and if people have free will. It's an amazing and underrated game.

Didn't think of TTP while watching the video, but you're right! What I love most about the implementation of QR codes in TTP1 is the ability to leave pre-composed QR code messages (possibly containing puzzle hints) for your Steam friends, or even your future self once you start a new game. Also, fun fact: if you switch the game to a different language, the QR codes also switch to that language. Meaning, if you try languages that contain lots of non-ASCII letters, such as CJK languages, the QR codes suddenly become a lot denser.

I then placed the QR code on the other side of the sliding tiles so that you can only read it after you've correctly assembled the picture. I made sure that the single missing tile would not mess up the QR code, but sadly the cuts did mess the code in a much more substantial way. You'd either have to extremely precisely cut the pieces with a machine of sorts to have the tiny cuts that snap perfectly once they fit, or just giveaway the code once the puzzle is solved manually which sadly defeats the point

When the coeficient u get is not the error, you are working out a solution that is different for both, as thr polynomial is wrong in one of the positions (the number being a 6 in this case) when you set the 6 as a variable the rest kf the polynomial is correct allowing you tk work out the initial value, which by default should be equal coeficient at both x = 1 and x = 2 given the last 2 digets. I hope that helped

But also, you can use the internet on a phone without ever interacting with a QR code, just open the internet browser and type words. That's how the internet works, QR codes as the only option just make using the internet far more annoying. I've probably used a QR code a total of less than 100 times in my life, only when they're the only option. Sadly those annoying little things are becoming the only option in a lot of places, much like no headphone jack on phones or less USB ports on laptops.

I bet almost 99% of people who watch this video dont know how big a role QR codes play, especially in China. Everything is QR codes here. All money is exchanged with QR, whether between friends or while shopping. The only way to join groups or add friends is to scan a QR. Even something as small as picking up delivery, ITS ALL THROUGH QR CODES! 🤯

<a href="#" class="seekto" data-time="1998">33:18</a> What a great idea. We could use three bytes to encode the color intensity of the red, green and blue channels of an image and then... oh, wait...
@gavinriley52323 күн бұрын
You could actually do it with less. Say it's a black and white image, just go with 1 & 0. So one byte gives you 8 pixels of information. It's 1/256 the storage requirements. The 3 bytes per pixel gives 256^3= 2^24= different color options PER pixel. That's certainly a bit much, especially for something simple like a menu. Instead we could do something like RRGGBB, this gives 64 color options. In a single byte. It's 1/3 the storage requirements. If we really want more options we could do something like RRRRRGGG-GGBBBBE. Where green is split between the two bytes and the E can be used as an error correcting digit. This gives 32k color combos. Its 2/3 of the storage requirements and gives us a ton of error correcting digits for free.

I hate using QR codes, but it's not the codes themselves - they're great. It's the implementation. Restaurant menus, unknown targets (possible scams), awkward placement. Sometimes I just want a URL I can remember and visit later, but all you're given is a QR to scan on the spot. Sometimes the phone won't scan it (or needs to be held still too long), or more often, I just don't want to get my phone out.
